I. INTRODUCTION
Water is a limited resource and is essential for
agriculture, industry and for creature existence on earth
including human beings. Lots of people don’t realize thetrue
importance of drinking enough water every day. Morewater
are wasted by many uncontrolled way. This problem is
quietly related to poor water allocation, inefficient use, and
lack of adequate and integrated water management.
Therefore, efficient use and water monitoring are potential
constraint for home or office water management system. So
to avoid this sever problem of water we have developed the
system. This system will keep the account of water usage of
every person or home. This system consist of two water
tanks. The tank 1 act asa main resource of water storage,the
tank 2 act as distributer of water to every home. This system
includes flow sensors which will keep the track of amount of
water given to the user. In the proposed system, we will use
the Atmega 328p microcontroller which is belongs to
Arduino platform. Along with the arduino 328 flow sensor
will measure the amount of water is supplied toeach society
member, if limit exceeds, solenoid valve will interrupt the
water. Sensor units installed at overhead and underground
water tank will update the real time status of water
availability on 16x2 alphanumeric LCD display. In this way,
by installing this low cost automated system water saving
can be encouraged by dividing the annual water taxation
according to usage of water. Society secretary can even
manage the water supply to specific member on occasion of
any event or celebration makes the system flexible for daily
use.
II. PROBLEM STATEMENT
Water demand is exponentially growing high with the
increase in population of the urban areas. Lots of people
don’t realize the real importance of water. Due to this the
water is wasted on a large scale by the people. So we have
developed the system which will keep the track ofamountof
usage of water by the people. Most of the societies have
manual supply of water whichleadsto spilling ofwaterfrom
overhead tank. So overcome this issue wehaveimplemented
the idea of smart water management with the help of IOT,
flow sensor, cloud monitoring etc. we can avoid wastage of
water. This system has effective impact on the usage of
water since it will keep the audit of usage of water.

data storage to store our data used as a cloud server.
V. FUNCTION OF COMPONENTS
[1]ARDUINO: It is an open source computer hardware &
software & software company project & user community
that designs & manufactures single-board microcontrollers
& microcontroller kit. Hardware means arduino circuit &
software means where we can type our program or
command the arduino. So basically it has two sides like
programing to control the project & hardware means
arduino device.
Fig. 2: ARDUINO UNO
It is tool for control the project or givethe instruction to the
circuit or project. Arduino UNO is very easy to use & it iscost
efficient & easily available in the market. The simple c
programing language is used & very easy to implement the
program like just connect the arduino to computer using
connector cable & implement the program.
[2]GSM MODULE: GSM is a mobile communicationmodemit
stands for Global System for Mobile communication. A GSM
modem is a specialized type of modem which accepts a SIM
card & operates just like a mobile phone. From the mobile
operator perspective a GSM modem looks just like a mobile
phones. When a GSM modem is connected to acomputerthis
allowsthe computer to use the GSM modem tocommunicate
over mobile network.
Fig. 3: GSM modem
While this GSM modemsare most frequentlyusedtoprovide
mobile internet, internet connectivity many of themcanalso
be used for sending & receiving SMS. It is used for
transmitting mobile voice & data service operate at the 850
MHz , 900 MHz, 1800 MHz & 1900 MHz frequency bands.
[3]LCD: Most common LCD’s connected to the
microcontroller are 16 x 2 & 20 x 2. This means 16 character
per line by 2 line & 20 character per line by 2 line
respectively.
Fig. 4: LCD
An LCD or Liquid Crystal Display, is a type of screen that is
used in many computers, TV’s, digital cameras, tablets & cell
phones.
[4]RELAY: It is electrically operated switch. Relay are used
where it is a necessary to control a circuit by a low power

Fig. 5: RELAY
Relays with calibrated operating characteristics &
sometimes multiple operating points are used to protect
electrical circuits from overload or faults. It used to shutting
off power supply when due limit is over.
[5]POWER SUPPLY: Power supply is a circuit it converts
unregulated DC into constant DC with the help of rectifier. It
converts AC supply into DC.
Fig.6: POWER SUPPLY
Its function is to supply a stable voltage to a circuit or device
that must be operated within certain power supply limits.
The output from the regulated power supply maybe
alternating or unidirectional, but is nearly always DC.
[6]Internet Of Things (IOT):Using the ThingSpeak.com we
get a free cloud server. This cloud server provides500Mbas
a storage.

applications.
[7]FLOW SENSOR:Accurate flow measurement is an
essential step both in the terms of qualitative and economic
points of view. Flow meters have proven excellent devices
for measuring water flow, and now it is very easy to build a
water management system using the renowned water flow
sensor YF-S201.
Fig. 8: FLOW SENSOR
This sensor sits in line with the water line and contains a
pinwheel sensor to measure how much water has moved
through it. The “YFS201 Hall Effect Water Flow Sensor”
comes with three wires: Red/VCC (5-24V DC Input),
Black/GND (0V) and Yellow/OUT (Pulse Output). By
counting the pulses from the output of the sensor, we can
easily calculate the water flow rate (in litre/hour – L/hr)
using a suitable conversion formula.
[8]SOLENOID VALVE: A solenoid valve is an
electromechanically operated valve. The valve is controlled
by an electric current through a solenoid: in the case of a
two-port valve the flow is switched on or off; in the case of a
three-port valve, the outflow is switched between the two
outlet ports. Multiple solenoid valvescan be placed together
on a manifold. Solenoid valves are the most frequently used
control elements in fluidics.
Fig. 9: SOLENOID VALVE
Their tasks are to shut off, release, dose, distribute or mix
fluids. They are found in many application areas. Solenoids
offer fast and safe switching, high reliability, longservicelife,
good medium compatibility of the materials used, low

actuator which is used most frequently, pivoted-armature
actuators and rocker actuators are also used.
VI. WORKING
The following system contains AVR Arduinoatmega
328, GSM Module, Flow sensor they are well synchronized
with each other. GSM module will trigger the Atmega 328
microcontroller which will get +5 volt DC supply from the
supply voltage. AVR will trigger the relay and relayy will
triggered DC motor pump an on indicationwillbeshowedon
16 x 2 LCD screen. As soon asthe motor starts the motorwill
start pumping water from ground tank to overhead tank
until the overhead level, senses the level of water. As the
level is achieved the flow sensor will send the command to
AVR to cut off the power supply of DC motor to avoid
overflowing of water from overhead tank an off command is
send to the LCD screen. A buzzer is used to show indication
sound as motor is on. Water is supply to the home through
overhead tank with the help of solenoid pipe which contains
control valve and flow sensor. Flow sensor will indicate the
amount of water supply through it whereasthe flow value is
used to restrict the access amount of water supply. This
whole data of water supply will be stored in cloud
monitoring system and can be managethroughGSMmodule.
This GSM module will send this data to cloud system using
packet data. The flow sensor sense the level of water tank in
overhead tank and when it reach to the level it sense the
level and send the on command to the relay and on
indication will be show on LCD then this data will be sendon
cloud server which would be made by us. The thing speak
gives us 500mb free cloud storage to store our data so our
data will be send on this cloud server with the help of GSM
module. GSM module consist of 3G/4G internet access with
the help of internet the data will be send on cloud server.
